Yes this is very much a goal, I've been a little low on OSS maintenance time but would also love to see this go in soon.
This isn't working :(
I'm testing with...
r, err := llms.GenerateFromSinglePrompt(ctx, model, prompt, llms.WithTools([]llms.Tool{tool_weather}))
var tool_weather = llms.Tool{
Type: "function",
Function: &llms.FunctionDefinition{
Name: "get_current_weather",
Description: "Get the current weather for a city",
Parameters: json.RawMessage(`{
"type": "object",
"properties": {
"city": {"type": "string", "description": "The name of the city"}
},
"required": ["city"]
}`),
},
}
and
r, err := llms.GenerateFromSinglePrompt(ctx, model, prompt, llms.WithTools([]llms.Tool{tool_weather}))
var tool_weather = llms.Tool{
Type: "function",
Function: &llms.FunctionDefinition{
Name: "get_current_weather",
Description: "Get the current weather for a city",
Parameters: map[string]any{
"type": "object",
"properties": map[string]any{
"city": map[string]any{
"type": "string",
"description": "The name of the city",
},
},
"required": []string{"city"},
}},
}
@jonathanhecl I’m not sure if this is the right thread to post your comment on. This is a post about supporting Ollama models with function calling using this library. The posted code does not have a reference to a model, so who knows if you are referring to ChatGPT, or anything else (this thread is explicitly about Ollama). The code also says “This isn’t working”, and has no error, and contains minimal context clues. I’d suggest you make a bug thread for your specific issue, and add errors and observations. Right now, it’s just like saying “the sky is blue”, which is … vague. And posting random unrelated comments in threads is a bit distracting for others.
I'm using Ollama (0.3.0)! but the tools are not working
model, err := ollama.New([]ollama.Option{ollama.WithModel("llama3.1")})
if err != nil {
log.Fatal(err)
}
prompt:= "what is the weather in london?"
var tool_weather = llms.Tool{
Type: "function",
Function: &llms.FunctionDefinition{
Name: "get_current_weather",
Description: "Get the current weather for a city",
Parameters: map[string]any{
"type": "object",
"properties": map[string]any{
"city": map[string]any{
"type": "string",
"description": "The name of the city",
},
},
"required": []string{"city"},
}},
}
r, err := llms.GenerateFromSinglePrompt(ctx, model, prompt, llms.WithTools([]llms.Tool{tool_weather}))
Response:
However, I'm a large language model, I don't have real-time access to current weather conditions. But I can suggest ways for you to find out the weather in London.
You can try:
1. **Check online weather websites**: Websites like AccuWeather, Weather.com, or BBC Weather provide up-to-date and accurate information about the weather in different locations.
2. **Use a mobile app**: There are many weather apps available on both iOS and Android that you can download to get current weather conditions.
3. **Tune into local news**: Watch a UK-based news channel or listen to a London-focused radio station for the latest weather forecast.
Please try one of these options, and I hope you find out what the weather is like in London!
I'm traying too, using GenerateContent, like this:
model, err := ollama.New([]ollama.Option{ollama.WithModel("llama3.1")})
if err != nil {
log.Fatal(err)
}
prompt:= "what is the weather in london?"
var tool_weather = llms.Tool{
Type: "function",
Function: &llms.FunctionDefinition{
Name: "get_current_weather",
Description: "Get the current weather for a city",
Parameters: map[string]any{
"type": "object",
"properties": map[string]any{
"city": map[string]any{
"type": "string",
"description": "The name of the city",
},
},
"required": []string{"city"},
}},
}
r, err := model.GenerateContent(ctx, []llms.MessageContent{llms.TextParts(llms.ChatMessageTypeHuman, prompt)}, llms.WithTools([]llms.Tool{tool_weather}))
if err != nil {
log.Fatal(err)
}
for i := range r.Choices {
fmt.Println(r.Choices[i].Content)
fmt.Println("FuncCall: ", r.Choices[i].FuncCall)
fmt.Println("GenerationInfo: ", r.Choices[i].GenerationInfo)
fmt.Println("StopReason: ", r.Choices[i].StopReason)
fmt.Println("ToolCalls: ", r.Choices[i].ToolCalls)
}
Return:
I'm a large language model, I don't have real-time access..... bla bla
FuncCall: <nil>
GenerationInfo: map[CompletionTokens:154 PromptTokens:22 TotalTokens:176]
StopReason:
ToolCalls: []
Is it running locally or are you using a service? Are you using JSON mode? Even if so, Ollama as a server does not just out of the box support tool calling in the same way as OpenAI. Try this same thing against a grok “tool use” llama model. You might get better results. It’s all in (1) how the output from the model gets parsed (largely depends on your service or the service hosted by others - Ollama json mode can help here but it’s no magic bullet), (2) how well trained the model itself is to handle functions, and (3) whether the system supports multiple concurrent tool calling or single tool at a time.
So, it’s a little more nuanced than “works” and “doesn’t work”.

The “hype cycle” says “Ollama supports tool calling”. But it’s a lot of hype at this point. Paid providers have tool use all over the place, but not Ollama yet. Ollama is free, so it’ll continue to be behind for just a while longer.

Can you support Ollama function calling in the same way as lang chain? Thanks.
